One thing still puzzles me.  This example defined the structure and
filled the matrix in one go.  My original example first built the graph
and then passed the graph to the matrix constructor.  I can get that
code to work, but only if I pass the domainMap and rangeMap to the
FillComplete calls for the graph *and* the matrix.  I don't understand
why the matrix isn't getting these values directly from the graph.
Perhaps I shouldn't be calling FillComplete for the matrix at all?
